Just wondering one weird thing about the 4-gear automatic transmission in
this car.

When engine and transmission are cold and after I started the engine and
start driving, the transmission stay lock in second gear (not the third, the
second gear...) for one or two hundred feet then finally goes in third for a
while as it warms up then the overdrive gear can kick in.
I do know many automatic transmission stay locked in third gear until they
warm up but... the second gear is new for me.

Is it normal?

Not a car to get immediately on a highway when it's locked in second gear
unless you run the engine in high RPM. Better warm it up on the service road

The manufacturer should warn people of this fact.

Nothing seems out of place. Holding 2nd gear instead of 3rd means
that it's trying to get up to operating temperature sooner. Nothing
wrong with that is there?

maybe I am wrong or misunderstanding you...

but i read that certain gears can only kick in as you get to a certain
speed.. try the manual.

immediately drive at higher speed, the transmission would upshift from 2nd
to 3rd.

I think the order of opperation is 23 miles and then 46 miles... or
something like that...

Transmission shifting has nothing to do with distance traveled. The
transmission ECU determines shift points, gear, and torque converter lock
based on engine coolant temperature, throttle position, engine RPM, road
speed, and transmission's current gear and torque converter status.

Nope, it won't! It *stays* in 2nd for a few hundred feet. I can rev the
engine to 5000RPM and it won't shift in 3rd.
Once warmed up, everything is ok as expected from from an automatic.

I have noticed the same thing on my 2006 Yaris. In cold weather the
auto will not shift from second into third until it has warmed up at
least a little. You end up driving down the street with the revs
really high because it doesn't shift. I don't know if this means
that you should let the car warm up. I thought that warmups for
modern cars were generally unnecessary.

If it is still in warranty, take it back to the dealer.
